The inflationary stabilization recently observed in Brazil brings a lot of changes in all aspects of the country’s economic life. In this work we look at the impacts on the stock market, specifically at Bovespa - the São Paulo Stock Exchange. We analyze the leading variables and statistics that describe Bovespa’s behavior, such as volatility and systematic risk, comparing the four years preceding and the four years after 1994, when the Real Plan was implemented. In order to eliminate exogenous influences, we use control series made with international Stock Exchanges Indexes. The results show that after 1994 there was reduced volatility, increased trade volume, reduced efficiency of the Bovespa Index and no changes in systematic risk.
